OIERA'I'ORS CHAIR.

Specification of Letters Patent.

Patented Oct. 1a, 1919. 7

Application filed February 4, 1918. Serial No. 215,318.

To all 071,017]. it may concern.

Be it known that I, HARRISON H. EATON, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Improvements in Operators Chairs, of wh ch thefollowing description, in connectlon with the accompanying drawings, isa specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to chairs. The invention is illustrated asembodied in a folding chair especially designed for the use of machineoperators.

The invention aims generally to produce a chair which, whileinexpensive, will be more durable and safer than chairs of this type nowgenerally used and which will still be convenient and comfortable forthe operator.

Another object of the invention is to provide a chair of the generaltype referred to, which, without sacrifice of other advantages, will beso constructed and arranged as to avoid objectionable blocking of orencroachment upon factory aisle space.

The illustrated construction and arrangement requires only a minimum ofaisle space when the chair is occupied, thus facilitating keeping thefactory aisles clear, and at the same time is such that whenever theoccupant leaves the chair, without special attention onthe part of theoccupant, the chair immediately assumes a position such as materially toincrease the aisle space, thereby facilitating aisle movements either offactory employees or of merchandise. This lastnamed characteristic is ofconspicuous value in the event of any sudden emergency resulting in ageneral exodus of. employees, particularly in case of panic from othercause.

With this object in view, an important feature of the invention consistsin providing a chair which can be secured to the floor in properposition relatively to the bench and which, when unoccupied, will assumea position immediately adjacent to the bench, preferably so that theseat will be partially under the bench and the back partially over it.In order that the rear legs of a chair so placed will not project intothe aisle, arrother feature of the invention consists in providing meansfor causing the rear legs normally to approach the front legs andaissuIne a substantially vertical position near: the bench and thusleave the aisle clear when the chair is unoccupied.

Other objects and features of the invention will be apparent when thefollowing description and claims are considered in connection with theaccompanying drawings.

In the drawings Figure 1 shows, in full lines, a side elevation of thechair in position to be occupied and also shows, in dotted lines, thechair tipped forward with the rear legs folded up toward the front legs;

F g. 2 1s a rear elevation of'the chair in the position indicated infull lines in Fig. 1;

Fig. 3 is a cross section of the back showing the means for securing theback-rest in adjusted position; and

Fig. 4: is a detail of the base showing, in cross section, the meansprovided for adj usting the chair either toward or from the bench.

Referring to the drawings in detail, 10 is the frame having front legs12 and a back 14 projecting therefrom. This frame, in-

cluding the extensions, is made, in the preferred c-onstruction,-ofangle iron or other suitable structural material bent at a plurality-ofpoints to give it the desired shape and, for convenience in manufacture,is made of two similar but oppositely shaped pieces secured together atthe topby means of the plate 16 and rivets 18. The front legs are 4pivotally supported to the base 20, the pivots being shown at 22. Whenin position for occupancy, the frame is supported by the rear legs 24pivotally connected to the frame at 26. The upper portion of the rearlegs forms one member of a toggle and a connect ing rod 28, pivotallyconnected to the rearlegs at 30 and to the base at32, forms the othermember of the toggle. Thistoggle, when straightened, will cause thechair to pivot about the pivots 22and move forward into the dotted lineposition shown in Fig. l; at the same time the rear legs 24 approach thefront legs so as to clear theaisle'for the purpose specified. A spring34 secured at one end to the frame and at the other end to therear'leg's causes the toggle to straighten and the chair to assume thefolded position, when the occupant rises from the chair. The base 20 iscomposed of two members 20 and20", the member 20 being secured to thefloor and the member 20 being mounted upon the member 20 for adjustm nttoward and from the bench, being locked in posit on by the b 3. an wingnut 38, as shown in-Fig; 4.

In the construction shown in the drawings, a seat 40 is secured to theframe 10 by means of two pieces of angleiron 4E2 bent as shown, and by aplurality of suitable fasteners 4d and 46, the scat A0 being secured tothe angle irons 4:2 in any suitable manner. V a a 1 The seat and frameare constructed and arranged to be secured together in any one of aplurality of relative locations in order to provide avertical-adjustment of the seat. A plurality of holes L8 are made in theex ensi-on '14 of the frame, and corresponding holes 50 are made in theextensions 12 forming the front legs. The fasteners 44 and 46 passthrough holesin the ends of the angle irons .42 and through any selectedset of holes 48 and ,50 to adjust the seat to the desired height.

T o the extension 14 which forms the back of itrhQ chair, aback rest 52is adjustably securedby the clamping plate 54:, the bolts 56 g and wingnuts'58, as shown in Fig. 3.

Having thus described-the invention, what is claimed as new anddesired'to be secured by Letters Patent of the United States is 1.- Afolding chair having, in combina.-' tion, a frame, front legs fixedlypro ecting rom the f ame, supporting mea s to w ich the front "legs arepivoted, .rearlegs pivotally connected to the frame, a pivotalconnection between said suppcrting'means and th ear legs, a seat carriedby the frame.

2, A folding chair having, in combination, a frame, front legs fixed-1yprojecting from the frame, supporting means to which the ryint legs arepivoted, rear legs pivotally connected to theframe, means for causingthe rear legs normally to approach the front legs, seat carried by theframe.

3. A folding chair having, in combination, a base, a frame havingextensions form.- ing front legs pivotally connected to the base, rearlegs pivotally connected to the frame, a connecting rod pivotallyconnected to the ba e. and the rear legs, means. for ausing he rear l gsn rm lly to a proach the front legs, and a seat carried by the ame nfixed relation theret 41 A folding chair, having, in combination, aframe, front legs projecting from the frame, supporting means to whichthe front legs are pivoted, rear legs pivotally con.- nected to theframe, a toggle, means for em nts! ret s may he wa ted tor frame andforming one member of a toggle,

a second toggle member connected to the rear legs and to the base, meansfor causing the toggle formed by said members to become straightened,and 'a seat carried by the" frame in fixed relation to the front legs.

:6. A folding chair, having, in combination, a frame composed ofstructural metal bent at a plurality of points to form the front legs,seat support and back of the chair, supporting means to which said frontlegs are pivoted, rear legs pivotally con.- nected to said frame and aseat carried by the frame. a w

A folding chair, having, in combina-r tion, a frame composed ofstructural metal bent at a plurality of points to form the front legs,seat support and back restof the chair, supporting means to which saidfront legs are pivoted, rear legs pivotally con-' neoted to'said frame,a seat, a plurality of fasteners for securing the seat tothe frame, theseat and frame being constructed and arranged to receive such fastenersin a pluralitylof relative locations.

I 8.'A folding chair having, in combination, a T-slotted piece providedwith means for securingit to a floor, a base portion, a slot in saidbase portion, means passing through the -T-slot and the slot in the baseportion for clamping the base portion in adjusted location, a frame,front legs projecting from the frame and pivota-lly mount ed on the baseportion, rear legs pivotally connectedto said frame, and a seat carriedby the frame in fixed relation to the front legs;

,9. An adjustable base for a chair having,

, on the base portion for securing a chair thereto. r

In testimony whereof I have signed my A name to this specification.
